BACKGROUND OF THE INVENTION

Parentage: ‘Macane017’ is the result of a controlled cross-pollination breeding program carried out by the inventors at their commercial nursery in Kirkcudbright, Scotland, in 2007. The inventors began by performing a controlled cross-pollination of Anemone rupicola (unnamed and unpatented), the seed parent, with Anemone hupehensis var. japonica ‘Pamina’ (unpatented), the pollen parent. An F1 seedling from said cross was grown to maturity and then pollinated with an unnamed Anemone hupehensis seedling with a dwarf growth habit and a pink double flower, developed by the inventors (unpatented). Said pollination was performed in an insect proof environment. Seed from said cross was harvested, then germinated, and the resulting seedlings were then grown to a mature size in a protected poly tunnel greenhouse. In 2008, the inventors selected the new Anemone cultivar due to its unique flower and bloom characteristics. This new and distinctive cultivar was given the name ‘Macane017’.

Asexual Reproduction: Asexual reproduction of ‘Macane017’ was first accomplished in 2008 by way of root cuttings at the inventor's nursery in Kirkcudbright, Scotland. After several years of experimentation, ‘Macane017’ was also asexually reproduced by way of meristematic tissue culture micro propagation at a plant tissue culture laboratory in the Netherlands. Successive generations produced from both root cuttings and tissue culture have shown that the unique features of the instant cultivar are stable and reproduce true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Macane017’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Anemone cultivar, ‘Macane017’. These traits, in combination, distinguish ‘Macane017’ as a new and distinct cultivar.

-   -   1. Anemone ‘Macane017’ exhibits a compact growth habit; and     -   2. Anemone ‘Macane017’ exhibits white flowers with alternate         petals colored dark violet-blue on the lower surface; and     -   3. Anemone ‘Macane017’ exhibits single flowers; and     -   4. Anemone ‘Macane017’ exhibits a long flowering season, from         summer through autumn when grown in Kirkcudbright, Scotland.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety of Anemone hybrid known as ‘Macane017’, based upon observations of one year old plants, potted into 17 cm nursery pots and grown outdoors at a commercial nursery in Kirkcudbright, Scotland. Plants were grown in full sun to partial shade using accepted fertility and irrigation practices for Anemone plants. With the exception of nematicides, no chemical pest control measures were employed. Furthermore, no artificial light or photoperiodic treatments were given to the plants. Observation data was recorded in July of 2017.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘Macane017’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, sixth edition, 2015.

A botanical description of ‘Macane017’ and comparisons with the parents and most similar variety of common knowledge are provided below.
